    TreePanel MVC onClick Node to Action


    I am using a TreePanel component and i have a problema to send to the action the id or name of the clicked node.

    The cshtml is like:

          m.ItemClick.Url = Url.Action("onClick");
    I load the treepanel with the SiteMap:

    public ActionResult PruebasRoberto()
        SiteMapNode siteNode = SiteMap.RootNode;
        Node root = new Node();
        root.Text = "Principal";
        root.AllowDrag = false;
        root.Expanded = true;
        ExtNetModel.LoadNodes(siteNode, root);
        return this.View(root);
    and i need to know the clicked node text, description or something in the action "OnClick".
    But i don't know how pass it to the action.

            public ActionResult onClick(Node o)
                return this.Direct();
    Any Idea?

    Hello @sishco! Welcome to Ext.NET forums!

    I believe you are missing the "pass the parameter" step. Look at how extraParameters is used in this example: DirectEvent connecting to WebService.

    Here's an explanation on why you need to manually pass these parameters if you are asking yourself: Hidden controls not responding to directevent actions post #3.

    Hope this helps!

    The final solution:

    The cshtml is like:

    .DirectEvents(m =>
          m.ItemClick.Url = Url.Action("onClick");
          // First the param "opcionMarcada"
          m.ItemClick.Before = "o.extraParams.opcionMarcada =;"; //This one is because i need to send as parameter the text of the clicked node.
          // Second the param "tabPanelName"
          m.ItemClick.ExtraParams.Add(new {tabPanelName="TabPanel1" });
    The controller code:

    public ActionResult onClick(string opcionMarcada, string tabPanelName)
                X.Msg.Notify(new NotificationConfig
                    Icon = Icon.Accept,
                    Title = "Working",
                    Html = opcionMarcada
                //To open a View in another controller.
                string nombreVista="../Grid/GridView";
                //To open a View in the same controller.
                nombreVista = "VistaBase";
                //Opening a tab in the tabpanel with the name in tabPanelName.
                var result = new Ext.Net.MVC.PartialViewResult
                    ViewName = nombreVista,
                    ContainerId = tabPanelName,
                    RenderMode = RenderMode.AddTo
                return result;
    With this code Works fine.

    See you something strange or that can be done by another better way?

    Hello! Thanks for sharing the solution for you! It might be useful for other people in the future! We really appreciate it!..

    As for a better way, can't really say for sure without knowing the full case scenario but as far as I can read, the code looks good; assuming line 13 of the controller code you provided was left like that just for didactic purposes. :)

    Yes. Line 13 is only for test and didactic purposes.

    Tanks for all.
